Could you perhaps add a new line (or two) before the exception itself? Right now it'll be displayed right after the text, so it'll basically be

Failed to generate log data: System.SomeException: Some message.
   at SomeNamespace.SomeMethod()
   at etc. etc.

I thought it would perhaps be better to clearly separate the exception from the message we're adding.

Makes sense, changed it.
